ICD-10 code for deafness

About coding deafness
The ICD-10-CM code for deafness is H91.9 (Unspecified hearing loss). The official index lists 32 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H91.9.
Within H91, choose H91.9 (Unspecified hearing loss) only when documentation doesn't support a more specific option: Ototoxic hearing loss (H91.0), Presbycusis (H91.1), sudden idiopathic hearing loss (H91.2), Deaf nonspeaking, not elsewhere classified (H91.3) and other specified hearing loss (H91.8).
To report this condition, pick the subcode that matches the documentation: H91.90 (unspecified ear), H91.91 (right ear), H91.92 (left ear) and H91.93 (bilateral).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Common questions about deafness ICD-10 codes
What is the ICD-10 code for deafness?
- H91.9 — Unspecified hearing loss (a header code; report a more specific subcode). More specific codes apply when the documentation supports them: Q78.0, T70.0, H90.2, H90.8 and others below.
What is the ICD-10 code for aviation deafness?
- T70.0 — Otitic barotrauma (header code; choose a more specific subcode).
What is the ICD-10 code for conductive deafness?
- H90.2 — Conductive hearing loss, unspecified.
What is the ICD-10 code for congenital deafness?
- H90.5 — Unspecified sensorineural hearing loss.
What is the ICD-10 code for emotional deafness?
- F44.6 — Conversion disorder with sensory symptom or deficit.
What is the ICD-10 code for functional deafness?
- F44.6 — Conversion disorder with sensory symptom or deficit.
What is the ICD-10 code for high frequency deafness?
- H91.9 — Unspecified hearing loss (header code; choose a more specific subcode).
Is H91.9 billable?
- No. H91.9 is a header code. Report one of its more specific subcodes instead.
